The Uniphos 350M Phosphine Alert gas monitor is a microprocessor based hand held instrument developed for the purpose of detection & monitoring of the target gas concentration on the hazardous locations. It employs gas sensor & advance electronic circuits. Gas sensor, when exposed to the target gas, produces current signal proportional to the gas concentration. This current signal is amplified by the electronic circuits, then digitized and shown on the alphanumeric LCD panel by the microprocessor.
